Tianjin days o project supervision consulting firm ) Summary : Through the description of mechanics and settlement calculations of Golden Bell cocoon , we design the Golden posite foundation for the settlement of foundation after the treatment, focused on solving: (1) just the pile to undertake the original load , changed to share with reinforced soil. reinforced soil produces numerous small positive arching effect and improve the foundation modulus, (2) dynamic load caused by the vibration caused by the settlement ofa three-dimensional grid to change the direction of the oscillation frequency so that does not produce settlement (3) improve the underlying
